Join Shaun Bryant for an in-depth discussion in this video Creating a dimension jog line, part of AutoCAD: Tips & Tricks.
- [Instructor] So, here we are in the world of AutoCAD and here's another tip and trick for you to use. We're going to look at the dimension jog line command, that dim jog line. You can see we've got a new drawing there for you, ANNOTATE_DIMJOGLINECommand.dwg because obviously it covers the annotate tab in AutoCAD on the ribbon. Now, what we're going to do is we're going to create a new dimension but it's not actually going to have like an endpoint. What it's going to reference is basically the distance from a grid line to the drainage pit that you can just see over in the top right-hand corner of the drawing.
So, there's our little drainage pit over there, and basically what we're going to do is place a nice long dimension line across all of those grids that goes to the center of that little drainage pit. So, make sure that you're in the right layer first of all. So, we're using A-ANNO-DIMS because it is a dimension, and then we're going to go to the Annotate tab over here on the ribbon. Now, we're going to place a linear dimension first. So, the trick is we go up here into the dimensions panel, linear dimension.
Make sure that your object snaps are on. We're going to zoom in on the intersection of the grids on that column just there. So, make sure you get the intersection snap and make sure it's on, and then I'm going to zoom out again, and as I come out I'm going to go all the way across here to the center snap of the circle that forms the drainage pit. So, I click there and as I come up now I can place that big long dimension. So, I'm just going to pan down a bit, zoom in a bit, and you can see it there, and I'm just going to place it underneath the grid bubbles about there and click.
So, there's my big, long dimension. And you can see it goes to the center of the drainage pit. Now, if I zoom in on that dimension, you can see it's a very random number there, 44,291 millimeters in our metric drawing. I don't want that text to appear there. I don't actually want a physical dimension distance so to speak. What I want is some text on that dimension line that says to drainage pit. So, here's what we do. We select the dimension, right click, go to Properties on the shortcut menu, and up comes the Properties palette.
So, obviously it's a regular dimension. I'm just going to drag the palette slightly to the left there so that we can actually physically see that dimension distance. I'm going to scroll down, and in the text override box I'm going to type in to drainage tank. Whatever terminology you wish to use. When I press enter watch the dimension, and that updates like so, and the dim text literally becomes text. It's not a value anymore. I'm going to close now the Properties palette, and hit escape to deselect.
Now, there's no actual physical dimension needed here as I said, so what we're now going to do is just put a dimension jog line in just near the words to drainage tank there just to kind of say that this is not an actual distance, it's not a physical distance, it's a piece of dimensioning that shows a position of something rather than a physical distance to somewhere. So, I go up to the dimensions panel on the Annotate tab on the ribbon. There's the Dimjogline command there, so I click and come into the drawing area like so.
Now, your jog line is actually specified in your dimension style. I will show you in a moment where that is. But I'm going to place the jog first, so I'm going to select the dimension to add the jog, which is this one, and then I can specify the jog location like so, I can just put the cross there anywhere along the line. I'm going to put it about there between E and D on the grids, and there's my jog there. So, when I zoom out a little bit you can see now that I've got a dimension there that is not physically dimensioning anything, it's just saying that the drainage tank is there to the right away from that J grid line on the left.
Now, you may use it for something else. It all depends on the actual context in which you use it. Now, I just want to jump into dimension styles quickly, so I'm going to click on the little arrow there on the dimensions panel, and you can see that we're currently using the diagonal 2.5 millimeter area which is there. I'll just click on modify, and what you've got is various settings in here in your dimension style. So, if I go to something like symbols and arrows, you'll notice that we've got a radius jog dimension there.
There's our linear jog dimension, that's the one I'm talking about. So, the jog height factor there is 1.5 times the text height of that particular dimension. So, I'll just cancel that and come out and close that. I'm not going to make the changes, and then I'll zoom in on our jog and basically this jog here is set up, the total height of that is one and a half times the drainage tank text there, just in case you need to know where that physical dimension comes from. So, that's your dimension jog line command, available to you in AutoCAD and you can use it in various contexts, including the context that I've shown you in this particular tip and trick video.
